- Ray diagram builder: converging lens simMove an object in front of a thin converging lens, draw the three standard rays yourself with a pencil and ruler, find where they meet, read the image distance and height off the grid and name the image, for all five object positions including the magnifying glass.
- Ripple tank: wave speed, reflection, refraction and diffraction simSet the dipper's frequency, freeze the waves with a strobe, measure λ over several waves and find v = f λ; then add a barrier, a shallow plate or a gap.
- Series and parallel rules simWire the same lamps in series or in parallel, drag ammeters and voltmeters into place, unscrew a lamp, and find the rules for current, p.d. and resistance from your own readings.
- Simple pendulum: timing, and finding g simSet the length, time 20 oscillations, fill the table and find g from the gradient of T² against l.
- Sound: vibrations, a medium and the oscilloscope simDrag the microphone and turn the oscilloscope's time-base and Y-gain to see louder = taller and higher pitch = more waves; read n waves over d divisions, work out T and f = 1 ÷ T and have each step checked; watch the air's compressions and rarefactions; pump the air out of a bell jar and graph the fading sound; and race a pulse through steel, water and air.
- Speed of sound by echo simClap in front of a wall, get in time with the echoes and time a run of them with a stopwatch, work out v = 2d ÷ t and see why one echo is too short to time by hand; then time a pulse between two microphones in air, water and steel with v = d ÷ t and compare the three speeds on one graph.
